Title: Improvements in or relating to a fluid actuated tool
IPC: B23B45/04
Filed: 1944-08-29
Abstract: 581,298. Rotary motors for tools. MOSS, E. W. (Ingersoll-Rand Co.). Aug. 29, 1944, No. 16423. [Class 110 (ii)] A portable rotary tool driven by a motor of the outwardly-sliding vane type is made reversible by twisting an extension 52 of a sleeve 25 containing alternative inlet ports 40, 41. The ports have arcuate extensions 42. Driving fluid is exhausted through ports 45 and chamber 46, leading to the atmosphere by way of ports 47 inside a crimped muffler 48. Admission of working fluid is controlled by a trigger 39 on a handgrip 22. A sleeve 26 is gripped between end plates 28, 29, which rotate in bearings 34. The angle of rotation of the sleeve 25 is limited by a pin 55 which engages one or,other ends of a slot in the sleeve.
Patent GB-462653-A (GB)
Title: Process of preparing a food product
IPC: A23L7/10
Filed: 1935-06-07
Abstract: A food preparation is obtained by cooking a naturally occurring starch- and cellulose-containing food substance to form a softened mass and then subdividing this mass to the extent which causes substantially complete separation of the food cells from one another and disintegration thereof and which breaks to pieces all the larger starch granules and substantially all the starch granules and also subdivides substantially all of the cellulose to particle size of substantially that of the said broken starch granules.  The subdivision may be effected by using a valve such as that used in homogenizing machines, a pressure of about 3500 lbs. per sq. in. being used with most vegetables and cereals. Other subdividing means such as a hammer mill or a colloid mill may also be used.  The following combinations of foodstuffs may be treated: (1) beets, asparagus, peas; (2) spinach, carrots, peas; (3) whole wheat, soya beans, tomato juice; (5) carrots, tomato juice, celery, beef liver, barley.  Combinations including fruits may also be used.  These materials are cooked, preferably in the absence of air, strained to produce fluidity and eliminate coarse particles and then, before or after mixing together, are subjected to the subdivision treatment. The products may be dried and sold as powders.  Foodstuffs already cooked and canned may be removed from the cans, subjected to the subdivision treatment and then recanned or dried and packaged for the market.  The products may also be sold in liquid form.  Specification 300,194, [Class 49], is referred to.

Title: Improvements in apparatus for sharpening the knives of slicing machines
IPC: B24B3/46
Filed: 1929-05-31
Abstract: 327,331. Fitzpatrick, H. D., (Maatschappij tot Vervaardiging van Snijmachines Volgens van Berkel's Patent en van Andere Werktuigen). May 31, 1929. Machine cutters, grinding in situ.-A manually actuated device is included in apparatus for sharpening the rotary circular knives of slicing machines, for controlling the grinding-element, and for locking it at will when in contact, with the knife. The grinding-wheel 2 is attached to a spindle 4, rotatably mounted in a sleeve 6, which can slide endwise in a stationary support 8. A friction pad 15 rests upon the support 8, through which passes a pin 9 attached to the sleeve 6. In the inoperative position, the handle 14 operates a cam 12, which acting on the pin 9 retracts the wheel 2. On giving the handle 14 a clockwise rotation, the cam first allows the wheel 2 to be forced into operation position by the spring 11, and may further be made to act on the pad 15, thus locking the grinding wheel in position. A further cam 16 may control the secondary wheel 3 and may coact with a friction pad. Specification 287,091 is referred to.

Filed: 1937-06-18
Abstract: 488,754. Toys. ARNOLD, C. June 18, 1937, No. 17008. [Class 132 (iii)] A toy in the form of a horse or other figure indicates the answer to an arithmetical problem by repeatedly raising and lowering a limb in accordance with a setting of mechanism in the toy to the answer it is required to indicate. A drum g loosely mounted on the spring motor winding axle d of the toy figure a is rotated by a key inserted in a square aperture h therein to position a numeral on the drum giving the answer in an aperture k in the bracket c and is held in the set position by a spring controlled lever m having an arm m<1>, engaging between transverse bars on the drum, and a release handle n. The spring motor driving mechanism is released by depressing the arm z on an oscillatable stop v to release the nose x thereon from the projection p on the disc q keyed on an axle o of the driving mechanism which then rotates for the catches r and s to engage the arms u, u<1> on the weighted thigh t to raise and lower it and for the projection p to engage between the transverse bars on the drum g to move the drum at each rotation of the disc q. When the zero numeral appears in the aperture k a cam 2 on the drum y engages with the stop v to position the nose x in the path of the projection p to stop the motor. The stop v may be operatively connected to the tail of the horse and operated to release the projection p by pressing on the tail.

Title: Apparatus for detecting faults in electric cables
IPC: G01R31/02
Filed: 1944-09-06
Abstract: 576,708. Detecting and locating faults. CALLENDER'S CABLE & CONSTRUCTION CO., Ltd., and GOODING, H. T. Sept. 6, 1944, No. 17066. [Class 37] Apparatus for the detection of an incipient fracture of a trailing cable conductor comprises means for making a circuit containing, in series, the conductor to be tested, a D.C. source, an inductive coil having an open iron core and capable of carrying a substantial current, an amplifier connected directly or indirectly across the coil, and a detector fed by the amplifier. The conductor 1 of the cable 2 is connected to terminals 4, 5 connected in series with a supply of direct current 3, and the primary winding 10 of a transformer 8 having an open iron core to avoid saturation by the direct current. The primary winding 10, which carries a heavy current, constitutes the inductive coil, the secondary winding 11 carrying a light current. A potentiometer 12 may be connected across the secondary winding, so that the input to an amplifier 9 may be adjusted. A neon lamp 13 is connected across the secondary coil to avoid excessive voltage at the telephone receiver 14, when the circuit of the inductive coil is made or broken. A1- ternatively a switch 15 in the primary circuit may be interlocked with a switch 16 in the secondary circuit, so that the latter is closed only after the primary circuit is made and is always broken in advance of the breaking of the primary circuit. A conductor of the cable to be tested is connected to the terminals 4, 5 and the cable is tapped vigorously at different points along its length ; if there is an incipient fracture, the resistance will be momentarily disturbed when the cable is struck near a break. This will cause an indication to be given at the output of the amplifier 9, resulting in a click or crackling sound being heard in the telephone receiver 14.

Abstract: 1364944 Transferring and conveying metal bars BRITISH STEEL CORP 13 April 1973 [13 April 1972] 17115/72 Heading B8A [Also in Division B3] Metal bars fed from a series of rails 9, under control of stops on pivotal arms 10, to a supply station 1, rest on helically operating drive rollers 14, and are driven axially by the latter through a grinding or turning machine 2. The bars are held in contact with the rollers 14 by the pressure of roller-carrying arms 16. From the machine 2, the bars then reach a receiver 3 comprising rollers 18 from which they are lifted by actuating arms 21, and are then held by arresting stops 27. When the next succeeding bar is fed by the arms 21, shoulders 25 on the arms 21 engage and displace the first mentioned bar over the stops 27, and it rolls down rails 28 to reach a drive section 6, under the control of arms (30) (Fig. 4, not shown). The bars are then successively driven through guide plates 33 defining a variable width channel, to a selector station 5. Here, manually operated control means, according to the observed or measured state of the bars, is operated either to place them, by an arm (36) (Fig. 5, not shown), on to the rails 9, and re-cycle them, or to feed them to a receptacle 7, by the action of an axially movable rod (39), and a pivotal arm carrying cone shaped lifter members (41).
